Set the available exits
Add the exits people can use during an evacuation. Give their width and mark any constraints that may reduce the usable width of the opening.
Set the pace of movement
How fast people move depends on the conditions during an evacuation. Pick a ready-made profile, or enter your own assumption if you want to run a particular scenario.
Set the number of people to evacuate
Set how many people you expect on site, and switch on stress scenarios to simulate peak crowding.

Evacuation progress over time
Below is the estimated number of people who may have left the site at each point. It is a forecast from the parameters you set, not a measurement of a real evacuation.
Time to clear the site: 18.4 min.
Evacuation pace
The length of each bar shows how many people — under the model used here — may leave the site in that time.
The calculations run in your browser. Nothing you enter is sent anywhere.
These results are indicative and rest on assumptions about how people flow. Real evacuation times may differ depending on conditions on site and on how the crowd behaves.
